Function
Crystal/ceramic resonator connection for main
system clock generation. When external clock
signal is used, it is applied to X1, and its
reverse phase signal is applied to X2.
Crystal connection for subsystem clock
generation. When external clock signal is
used, it is applied to XT1, and its reverse
phase signal is applied to XT2. XT1 can be
used as a 1-bit input (test).
System reset input
Operation mode selection pins during the
PROM write/verify cycles.
Normally connected to V
